Abstract

The invention relates to pine nut shell gas-phase adsorption active carbon, which is prepared from the following raw materials in parts by weight: 150 to 160 parts of pine nut shell, 3 to 4 parts of graphene, 10 to 15 parts of attapulgite, 8 to 10 parts of ferric trichloride, 8 to 10 parts of sodium perborate, 10 to 15 parts of citric acid, 4 to 5 parts of modified diatomite and an appropriate amount of water. The pine nut shell is adopted as a raw material to produce the active carbon. The pine nut shell has hard texture and moderate specific gravity and is likely to form a fine pore structure after being carbonized at a high temperature, the weaknesses of a traditional method can be overcome and the active carbon is suitable for the gas adsorption; by adopting the attapulgite, a sterilizing, deodorizing, moisture absorbing and mildew preventing functions can be achieved and organisms can be catalyzed and decomposed; by utilizing the ferric trichloride, oxidization and desulphurization can be realized; due to addition of the sodium perborate, the oxidization decoloring function be realized and ecological oxygen can be realized; and the pine nut shell gas-phase adsorption active carbon is safe, healthy, low in cost and particularly suitable for purifying the air of a living environment.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a pine nut shell gas phase adsorption activated carbon and a preparation method thereof. Background technique [0002] At present, air pollution has seriously affected people's production and life, so air purification has to be taken seriously. Adsorbents are often used in air purification, mainly activated alumina, activated carbon, and adsorption materials developed for selective adsorption of certain components. However, most of these adsorbents have limited adsorption capacity, and different adsorbents need to be studied according to different requirements to play the best role. At the same time, look for new raw materials to enhance the adsorption effect and save costs. With the continuous improvement of people's requirements for quality of life, it is also necessary to provide adsorbents that are beneficial to the human body. Contents of the invention [00...
